Two decades ago, filmmaker Yair Lev made Hugo, a film about his father, a survivor of Auschwitz, in which the older man revealed his most passionate belief: “It is most important for a man to be strong.” Now, Lev returns with Hugo 2, the result of his ruminations about his thin and frail son: Would he have survived his grandfather’s experience? A moving film that captures the inherited past and its implications, from survivor to child to grandchild.
